Application medNevember s, ieaalseriai 'Na/"asuma ivnenewed auneaigied .My invention relatesV to yharvesting ma- *n chinery and is particularly pertinent to he'adbroken away, the spout of a header according ers provided withspouts for discharging the cut grain.

' In most headers, there is provided a traveling belt known as a draper, for receiving cut grain and either conveying itV thru a draper extension or spout to the separator unit of a combined harvester or discharging it on the ground in windrows, in whichvlatter instance the mechanism is "usually termed a windrow header. Itis customary that the Ygrain `being ,carried be confined to the spout by sides which form an vopen trough or U- shaped channel with the draper at the bot# tom thereof. The sides are especially useful in restricting light iiuy grain to the draper, and are eminently satisfactory -when kthe length of the grain is less than the width of the draper. But for grains which grow to. a considerable height and particularly when long clover is being handled, congestion occurs on the draper, particularly inthe spout, due to the inability of the grain or'clover to extend across the draper without interfering Vwith the spout sides.

It is therefore an object of my invention to provide a spout which will accommodate eX- tra long grain or clover as well as normal or understood that do not limit myself to such form since the invention, as set forth in the claims, may be embodied in a plurality of forms.

In th'edrawings: l 1 s Fig. shows in perspective, with yportions tdmy invention. 1 Fig. 2 is ai cross section, the plane of whichl is indicated by the line 2 2 'ofgFigl l. In its preferred form, thfespoutside of my invention is preferably mounted on the spoutin such a manner that it can be positioned to forman enclosure ofthe draper or can be positioned to lforman extension of the draper fortherpassageof long grain or clover,

In the embodiment of my invention disclosed inl the dra-wings,.the headerusually includes a framework 6 convenientlyvmadeof nested angle irons 7 kand 8 providing chan# nelsin which the upper Yrun and lower rungof a draper'9 are guided. The'angles 7 and 8 are preferably parallel and ordinarilyr eX-y tend substantially horizontally. y At the leading edge of *A the framework `6 is usually mounted a mowing device such as a sickle 11 PATENI OFFICE Y.

which cuts the standing 'grain or clover'and permits it to fall on the draper.' V'The rear side of the header ordinarily is provided with avbackboard 12 upstanding 'from the framework and designedtovconfine the grain or clover to the draper.

The draperitself ally of canvas or similar fabric, onwhich4 at intervals are affixed sticksflll. The draperis usually passed over a roller at each end and is propelled by suitable mechanism, not shown. `The discharge end of the draper preferably is supported by a'spout framel work 16 usually including two pairs vof knested anglesl? and 18'joined together. These are ordinarily disposed to continue theangles 7'A and 8.V The spout framework is preferably hinged to the header framework 6 on a trans# verserod 19 passing between theupperand lower runs of the draper ,9. vThe backboard 12 is continued in the spout by `a spout side 21 fastened to the framework 16 and sliding:

over the backboard when the spout is raise comprisesa belt, gener- Y j e yand lowered around rod 19. In conventional constructions, a similar side is arranged parallel to the spout side 21 and on the leading edge of the draper to aid in confining the I grain traveling on the draper.

' kIn accordance with my invention I preferably provide a different sort of spout side on the leading edge of the header. This spout side usually is a plate 22 of sheet metal reenforced by suitable angles 23 and is secured to the spout framework 16 by hinges 24 and 25. The hinge axis is substantially in the same plane that the upper run of the draper 9' occupies. This movable spout side can optionally be positioned upstanding from the framework 16, as shown by the dotted' lines of Fig. 1, orv it can be positioned in substantially a horizontal plane to form a continuaf* f tion of the upper run of the draper as is shown by the full lines in Fig. 1. For retaining the side 22 in either eXtreme positionthere is preferably provided a cam surface 27 on one Aof the hinges against which a stif leaf spring 28 bears. The side cannot be, accidentally jarred. from position but can easily be adjusted. The ingress of grain to the spout isfaeilitated inv either position of the4 hingedV side by a flaringleading. edge of In the usualposition of the spout side, the plate 22 extends upwardly, and short and normal grain is properly confined and protested fromr wind. When the machine is operatedv in long grainv and especially in onv the hinges- 24 and25 into a substantially horizontal position to form an extension of the upper run of the dra-per. The long grain or clover-then can extend over the draperand be supported by the spout side.

I claim:

1. In a header, a spout framework, a draper arranged to run onnsaid framework, a sheet metal spout side pivoted'on said framework to form a coplanar extension ofvk said draper, the leading edge of said spout side beingA fiared, hinges connecting the spout sides with the framework, and resilient means acting on; thehinges to position the spout side. l

2. Ina header, a spout framework, a spout side at one side of the framework, a second spout side having a fiared leading edge movablyconnected with the opposite side of the 5@ framework, hinges connecting the second spout side with the framework to permit the second'spout side to swing on the frame, said hinges having' cams formed thereon, and,

leaf springs adapted to engage the cams to position 'the' spout side with respect to the framework. Y

3. In a header, achannel iron spout frame'- work, a draper arranged to run on the framework, a reinforced' sheet metal spout side D having a flared leadingvedgepivoted on the long clover,;the. movable spout side is rotated
